Specification of To all ugliom it concern; 1

.Be' it known that I, MALCOLM P. RYDER, a

' citizen of the United States, and aresident ofWhite Plains, in the county of Westchester and State of New York, with post oflice address 1 Highland avenue, have inventedcertain new and useful Improvements in Generators of Intermittent Electric Cur rents, of which the following is a specification.

My invention relates to apparatus for generating intermittent electric currents through changes in the magnetic fluxthrough a generating coil,-.said changes being produced by the movement 'of a 'massor masses of magnetic material,such as iron, and. which will, for convenience, hereinafter be termed an'armature or armatures.

The object of my invention is to produce a high-voltage currentwith a smallninnber of I turns of wire by employing generating coils '25,. to interrupt and shunt the magnetic flux, 'a's combined with two sources of magnetic flux adapted respectively to produce flux in opposite directions through said coils, and combining with them armatures cooperating hereinafter set forth.

My invention consists further in the spe} cial combinations of generating coils, sources ofmagnetic flux and an armature or arma tures combined and operating as hereinafter more part cularlydescribed and" then Specitied in the claims.

In carrying out my invention, the sources ofina-gnet-ic flux consists preferably of per- ;nianent magnets, but I do not limit myself totlie use of any particular source of magnet1c-flux..\\ hen permanent magnets are employed, my invention is also useful in preventing reduction of the sti'eitgth of said magnets from changes 'in their magnetic condition. This result is effected through so combining the magnets and armatures that changes in the iiia'gnctic reluctance loctween the poles oi the magnet are prevented.

Said armature 3' has a two-fold eii'ect in thismovement, since it not only 'conspires with armature 3 in stopping or reducing the flux from the source 2' by shunting said flux from the circuit through the coils coinci- 'dently with the interruption of the flux produced by armature 3, but also establishes a armature 3' then performing the functionassigned to armature 3 inthe description of operation just given, while armature 3 acts a's'did the armature 3, the only difference being that the flux through the coils is established from magnet2 instead of from magnet .2. 1 While 'thdcombined or cooperating net.

action of the armature may be secured by a reciprocating mechanism such "as will be now described adapted to produce a sudden or violent detachment or change. of position of one armature only, as for instance, armamm 3, the principles of my invention may obviously be carried out by mechanism which would secure the same violent or sudden movement of both armatures in. their movement away from the cores of the mag- Referring to Figs. 2, 3, 4: and 5, 56 indicates a casing within which is suitably mounted the parts of the apparatus Reciprocation of the armatures isproduced by a reciprocating rod 11 working in cross heads or cross bars of aframe 14. Said rod is actuated by means of a cam 10 secured on rotary shaft 9 driven by any means. Said cam engages with the upper end of the rod and forces the same down against the action of springs to be resently described. i the cam passes the end of the rod, the springs are released and the rod suddenly rises, carryingwith it the As the cam continues its rotation, it forces the rod down a ain car rying' the armatures in a reverse irection.

Armature 3 consists preferably of laminated iron, the laminations of which arefastened together by screws 20 between the heads of a spool 29 through which the rod 11 may move freely. Rigidly secured to the rod- 11 is a collar 24 adapted to engage the arma- 1 ture on the s 001 2-9 from beneath, when the v rod rises.

said armature and a-collar 17 'adjustably nterposed between the top of fastened to the 'rod by set screw 16, is. a spring 18'w'hich is compressed by theaction" of the cam 10 on the rod. Armature'ii may be similarly constructed and secured to a spool 29 through which the rod passes loosely. Between the under side of the spool 29 and a collar 27 adj ustably secured to the rod by screw 28 is a second spring 26. A collar 25 fastened to the rod 11 limits the upward movement of the armature 3 on said-rod under the action of spring 26 and serves as a means for positively moving the armature away from the cores, when the rod is depressed. The cores for the coils may be also laminated and fastened in split blocks of iron 32 and 33 at opposite ends of the coils by means of the screws 30, 31 which clamp the" split end of the block upon the '-cores., To the outer ends ofthe blocks 32 33 the poles of the magnets 2, 2, are fastened by screws or'ot-herwise and said magnets themselves may be secured or supported in wooden. blocks within the case in "any suitablemanner. The bearings for the reciprocating rod 11 are indicated at 12 and 13. Each source of magnetic flux is shown as comprising two permanent magnets, 1- I though obviously a greater or less number might be employed for each source. b l

The operation of the mechanism combined with the two armatures and .the two sources of magnetic flux would be as follows: the moving parts being in the position shown in Fig. 2. The flux of magnet 2 is shunted from thecoils by armature 3 but the flux from magnet 2 flows in a circuit through thecoils and through said armature. Whenthe rod 11 is released by the cam, spring 18 which is under compression moves the rod upward suddenly and the collar 24 detaches the armature 3 while the armature 3' is carried up by the rod into contact with the opposite ends of the cores 5. The result is that the shunt for the flux of magnets2 around the coils" is suddenly broken, while at the same time'the circuit for the flux of magnet 2 by way of said armature 3 is also broken and the magnet 2 is now able to produce the magnetic flux insaid coils in the opposite direction to that formerly produced by magnet 2. Its action in establishing such reversal of mag netic flux is assisted by the armature 3 which not only establishes a path for said flux at-the'opposite end of the cores, but also removes any opposition to the change of flux from that established by magnet 2 by shunting the magnetic flux of said magnet 2. from the coils. As the reversal of magnetic flux takes place in a very short time; a sudden impulse of current is generated in the coils 1. The sudden reversal of magnetic flux thus produced by the cooperative action of the armatures makes it can be secured by simply reducing'the mag net-ic flux to zero by the movement of an armature as in the previous construct-ion or combinationof armatures, generatlng 00115" and sources of magnetioflux describedin my prior application before referred to. As the rod 11 moves downward under the action of the cam, it reverses the movements of the two armatures and brings'armature it detaches armature 3. This movement being a rather gradual movement, will not,

of course, produce a current of such high potential as is produced when the rod is.

released. As will be obvious,the magnetic.

circuit of each magnet is closed at all times and hencethe magnetic reluctance will not vary so as to produc injurious fluctuations in the strength of the magnets with a consequent gradual deterioration the permanent magnetism.

When theapparatus is used for generating the igniting spark in internal combustion engines the shaft 9 may be driven by ,a sprocket wheel 50 or other wheel geared to the engine shaft. In such case, I use the following timing'mechanism to permit the time of the spark to be changed: Shaft 9 is provided with an inclined slot 5l extending preferably through said shaft and through said slot projects a pin or key 52 which engages a longitudinally extending key way .or groove within the hub of the wheel 50. I Said pin is carried by a rod 53 which rotates with but slides axially within the hollow shaft 9 and is axially adjusted by means of a pivoted yoke 54 that engages the groove in a sleeve 55 fixed to and rotating freely with the rod. Aswill be obvious, axial movement of the rod changes the angular relation of the wheel 50 to the shaft 9 and so varies the time of the spark with relation to the cycle of action of the engine which drives the wheel 50. The yoke 54 is operated manually as in the caseof any spark timing device for gasolene engines.

A binding post and tip specially adaptedto prevent accidental disconnections of the tip comprises a metallic shell 60 having a transverse perforation as shown and a spring actuated pin or rod 62" having a similar transverse perforation or opening adapted to be brought into registry with the transverse perforatlons or openings in the shell. To the pin or rod 62 is .connected a spring 64 within the shell which tends to draw the pin down. The said pin may however be raised by its head to bring its opening into registry with the openings in the shell for the purpose of permitting the insertion of the contact pin or tip 66. The latter is turned down to provide the two shoulders indicated at 67. After the tip has been inserted and the pin or rod 62fseleased, said pin settles down upon there}.

on the latter prevent its withdrawal by en'- gaging with the pin or rod 62. The shell .60 may be fastened within an insulating "bushing 68 by means of the rod 69 extending from said shell down through the insulatior 70 of the bushing.- Electrical connection with the binding post may be made through said rod which, as indicated, rests upon the terminal'for the wire forming the coil.
